The Parker Library is a library within Corpus Christi College, Cambridge which contains rare books and manuscripts. It is known throughout the world due to its invaluable collection of over 600 manuscripts, particularly medieval texts, the majority of which were bequeathed to the college by Archbishop of Canterbury Matthew Parker, a former Master of Corpus Christi College. Collection The library houses a significant proportion of Anglo-Saxon manuscripts, including the earliest copy of the Anglo-Saxon Chronicle (Version A of the ASC, Corp. Chris. MS 173, known as the Winchester Chronicle or the Parker Chronicle, c. 890), the Old English Bede, and King Alfred’s translation of Pastoral Care (a manual for priests), as well as the Latin St Augustine Gospels, one of the oldest bound books in existence. The collection also includes key Middle English texts, such as the Ancrene Wisse, the Brut Chronicle and Geoffrey Chaucer's Troilus and Criseyde. Other items include medieval travelogues and maps, apocalypses, bestiaries, one of the oldest pieces of extant written music, and illuminated manuscripts, such as the two giant Romanesque bibles of Bury (c. 1135) and Dover (c.1150) and the Chronica Majora by Matthew Paris (c. 1250). A full, alphabetised catalogue is available here. Its most prestigious possession is the St Augustine Gospels (Cambridge, Corpus Christi College, Lib. MS. 286), believed to have been brought to England by the Augustinian mission, sent by Pope Gregory I to convert the people of Britain in AD 597. It is an illuminated Gospel Book created in Italy in the 6th century and has been in England since soon after its creation. It has 265 leaves measuring about 252 x 196 mm, and is not entirely complete, missing pages with miniatures in particular. This manuscript is the oldest surviving Latin (as opposed to Greek or Syriac) illustrated Gospel book, and one of the oldest European books in existence. Although the only surviving illuminations are two full-page miniatures, these are of great significance in art history, as so few comparable images have survived. The Gospels are used in the enthronement of the Archbishops of Canterbury today and are transported to and from Canterbury for this occasion by the Master and college representatives. In October 2016, Christopher de Hamel announced that an 11th-century Anglo-Saxon psalter (Cambridge, Corpus Christi College, Lib. MS. 411) in the library's collection had "undoubtedly" belonged to Thomas Becket, and it was possible that Becket was holding this
